Hello,<br class="">
<br class="">
I'm having an issue where kamailio is not sending the failure reply
as I would expect when receiving calls from a certain provider.
Kamailio sends the 403 response on calls from other providers. The
big difference I see is that the "problem" provider is using compact
headers. I am trying to force the 403 response to be sent for
testing purposes but I just can't get it to reply to this one
provider. <br class="">
<br class="">
I've included traces and configuration excerpts below. Any help is
much appreciated!<br class="">
<br class="">
Problem Call (No Reply Sent):<br class=""></div></div></blockquote>There must be something missing here. Without a response, there would be no ACK. </div><div><br class=""></div><div>/O<br class=""><blockquote type="cite" class=""><div class=""><div text="#000000" bgcolor="#FFFFFF" class="">
